13.3 Register
Descriptions
The SCI has the following registers for each channel. Some bits in the serial mode register (SMR),
serial status register (SSR), and serial control register (SCR) have different functions in different
modes
normal serial communication interface mode and smart card interface mode; therefore,
the bits are described separately for each mode in the corresponding register sections.
•
Receive shift register (RSR)
•
Receive data register (RDR)
•
Transmit data register (TDR)
•
Transmit shift register (TSR)
•
Serial mode register (SMR)
•
Serial control register (SCR)
•
Serial status register (SSR)
•
Smart card mode register (SCMR)
•
Bit rate register (BRR)
